Abstract
A simplified single cell apparatus and method for removal of suspended impurities in liquids using gas flotation and filtration is provided wherein the method and apparatus are preferably directed to induced gas flotation separation of suspended impurities in combination with a filter media for filtration removal of remaining suspended impurities. A filter media is contained within the single cell apparatus such that liquid exiting the vessel must pass through the filter media after having been subjected to flotation treatment.
